Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

A Universal Method for Managing E-Mail Attachments

Publishing Venue

IBM

Abstract

E-Mail services currently lack a universal method for managing e-mail attachments. Mail servers and e-mail programs utilize large storage space to store both the e-mail and the e-mail attachments. The moment the e-mail author sends the e-mail with the attachments, the hosting mail server creates a storage space for the attachment until such mail reaches the intended recipient(s). With the growing popularity of e-mail communication in today's society, there has also been a growing need to send e-mail with a large size attachment to a group of recipients that may range from one to a hundred or more. Management of such large size attachments that may be distributed to many recipients across the continents pose storage problems, performance degradation and viral threats. This invention describes how to solve the problem of sending e-mail attachments with e-mails, introduces an effective and optimum method of storing attachments and accessing such using links in the e-mail.

A Universal Method for Managing E -Mail Attachments

Scenario

Consider a hypothetical example of an e-mail with a 400-page document attachment
that is being sent to 120 recipients. Also consider having the recipients' mail and
attachment stored on different e-mail servers. Assuming that there are 100 mail servers
involved in this e-mail distribution. Each of the 100 mail servers receiving the e-mail will
have to store the 400-page document and distribute them to the individual e-mail
recipients. Figure 1 shows an example of 1.3 MB worth of e-mail attachments sent to
20 recipients. It will require a total of 1.3 MB * 20 recipients or 26.0 MB of storage space
for this e-mail attachment.

The scenario just described also highlights the performance problem that causes
networks to be bogged down by large attachments circulating with the e-mail. There is
also the risk of proliferation of viruses because the attachment circulates to all the
network links and mail servers and personal computers of the recipients.

The invention is a Universal Method for Storing E-Mail Attachments. This invention
provides a universal mechanism where an e-mail program can send an attachment to a
remote storage location that can either be centralized or distributed. It also provides a
universal mechanism where an e-mail program can retrieve an attachment from a
remote storage location that can either be centralized or distributed. Storing of e-mail
attachment remotely and retrieving of such remotely allows storage resource usage to

circulating large sizes of attachments that slows down network traffic. Storage resource
optimization can be done by implementing the Web Services technology with e-mail
attachments. The invention provides a capability to Virus Scan att...
